IMPROVED APPARATUS FOR THE MANUFACTURE OF GAS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, JOHN C. Gain of Homer, in the county of Cortland, and State of New York, have invented certain new and useful improvements in Apparatus for the Manufacture of Gas; andI do hereby declare that the following is a full and exact description thereof, reference being bad to the accompanying, drawing, which represents a central vertical section of my improvement.

. My invention is designed for use in single families or buildings, whereby gas light can be supplied to all requiring the same, at a trifling expense, however remote they may be from towns which are supplied with it from a general manufactory in the ordinary manner.

The invention consists in the arrangement and use within a'common stove ofa retort forthe distillation of gas, especially that designed for illumination; in-the special manner of arranging the same, whereby the retort can be readily elevated to the top and colder portion of the stove when its use is notrequired; and in combination therewith the arrangement of the purifying vcssels under the stove. p

In the drawings A represent-s a'stove, which maybe of any ordinary construction, and Baretort, arranged therein above the fire-pot C. D is a pipe, ascending from the retort through a suitable opening in the top of the stove. E is the feed pipe, opening into the top of D, as shown, and connecting with the reservoir containing the oil, or other material to be distilled, which may be situated in the same or any other apartment, as most convenient. is the gas pipe, into which thogas from near the top of pipe D escapes, and by 'which it is con ducted (preferably) to the purifying vessel or vessels H H, constructed and arranged under-the base of the stove, and forming a support therefor. These vessels or compartments may be formed at each corner,as shown, with the base of the stove resting thereon, with pipes communicating from one to the other, as shown in dotted lines, so that the gas may pass through two ormore of them if required before being conductedito the gasometer. The compartments H are partiallyfilled with any of the ordinary solutions or mixtures that'are employed for purification. When the generator 13 is not required to be used it is elevatedto thetop of the stove, (shown in red lines,) the pipe D sliding through the opening in the top of the stove, and the gas pipe F, being constructed with a suitablc sliding joint, as represented at'I, with a liquid packing, or in any other suitable manner that, will allow the necessary adjustment of the upper portion of the pip'c.- This removes the retort tothe comparatively cool portion of the'stove; where the heat is insufficient for distillation. The retort may be constructed in any suitable manner which may vary to adapt it to the different substances that may be required to be distilled, although itis designed more especially for oils, and it may be provided with any suitable means for removing the residuum therefrom. The apparatus is designed to be connected with a gasometeir, in which the gas that is distilled during the day when the stove is in use'for the ordinary purposes of warming, &c,., may

accumulate for consumption during the evening. The use of my improvement makes gas light accessible to'all,

although they may reside in localities, such for instance, as the country and small villages, where they could not be supplied with it from a general man-ufactory, and at a trifling expense compared with that required to manufacture it by means of a furnace designed for the specialpurpcse alone. The amount of gas required for illumination at night can be readily distilled during the day and evening without the use of any additional fuel. The apparatus is simple, and is mostly concealed within the stove. The arrangement of the purifying vessel or vessels'under the stove'economizes space that is-usually unoccupied.

What I claim as my invention, and desire to secure by Letters Patent, is'- The employment of a retort within a common stove for the distillation of gas, substantially as set forth.

I also claim the special combination and arrangement of the retort B, pipes D, E, and F, and sliding joint I, with the stove A, whereby the retort may be elevated to the top of the stovewhen not required for use, substantially in themanner and for thepurpose specified.

I also claim the arrangement of the purifying vessel or vessels H, under the. stove, in combination withthe retort B, and connecting pipes, substantially as and for the purpose described. I In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
